Kleberg County · Borregos (Consolidated Gas) field · Vertical

King Ranch Borregos #308 (API 42-273-00107) is a plugged well in Kleberg County, plugged January 20, 2012, last operated by Exxon Mobil Corporation.

The RRC has issued 5 drilling permits between 1981 and 1993, permitted to 7,354 ft.

It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.

Its 4 leases have reported 299 barrels of oil and 769K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
